Debian image built from contrib/debian-iso doesn't load

[arnegoetje]

I have built the debian jessie iso image from the contrib/ directory and tried to load it onto a AS5812-54X. But when ONIE wants to load the kernel with kexec, nothing happens after printing "Starting new kernel" to the console. I have even rebuilt ONIE for the AS5812-54X and upgraded ONIE on the switch.

Sounds like a serial console configuration issue.

You might have to change the serial console parameters for your platform. The settings in the source code are for the kvm_x86_64 machine, which may be different from the Accton AS5812-54X.

The relevant line to double check is here: https://github.com/opencomputeproject/onie/blob/2018.02/contrib/debian-iso/cook-bits.sh#L82
